They have not valued Allah with His true value, when they said 'Allah has never sent down anything to a mortal. ' Say: 'Who, then sent down the Book which Moses brought, a light and guidance for people? You put it on to parchments, revealing them and hiding much, you have now been taught what neither you nor your fathers knew before! ' Say: 'Allah. ' Then leave them, playing in their plunging. (91)

And this is a Blessed Book which We have sent down, confirming what came before it, in order that you warn the Mother of the Villages (Mecca) and those who (live) around it. Those who believe in the Everlasting Life believe in it and preserve their prayers. (92)

Who is more harmful than he who invents a lie about Allah, or says: "It has been revealed to me," when nothing has been revealed to him? Or he who says: 'I will send down the like of what Allah has sent down! ' Would that you could see the harmdoers when death overwhelms them! With hands outstretched, the angels (will say): 'Yield up your souls. You shall be recompensed with a humiliating punishment this Day, for you have said of Allah what is untrue and you grew proud against His verses. (93)
